Working With Sfp+ Modules And Fiber Optic Cables; Guidelines For Using Sfp+ Modules; Removing Sfp+ Modules - Dell PowerVault MD3800f series Deployment Manual

Working With SFP+ Modules and Fiber
Optic Cables
Each storage controller can have up to four FC host ports. A small-form-factor pluggable (SFP+) module
is used to connect a host port to a host or switch. The SFP+ module is inserted into the port, and then a
fiber optic cable is inserted into the SFP+ module. The other end of the fiber optic cable is connected to
an optical interface connector either in a FC HBA on a host or a switch. SFP+ modules are laser products.
WARNING: Data processing environments can contain equipment transmitting on system links
with laser modules that operate at greater than Class 1 power levels. Never look into the end of
an optical fiber cable or open receptacle

Guidelines for Using SFP+ Modules

The storage array requires SFP+ modules. SFP+ modules convert electrical signals to optical signals that
are required for FC transmission to and from RAID controller modules. After installing the SFP+ modules,
fiber-optic cables are used to connect the storage array to other FC devices. Before installing SFP+
modules and fiber-optic cables, read the following information:
• Use only Dell supported SFP+s with the Dell PowerVault MD3600f series storage arrays. Other generic
SFP+s are not supported and may not work with the storage arrays.
• The SFP+ module housing has an integral guide key that is designed to prevent you from inserting the
SFP+ module incorrectly.
• Use minimal pressure when inserting an SFP+ module into a FC port. Forcing the SFP+ module into a
port may damage the SFP+ module or the port.
• Use minimal pressure when inserting an SFP+ module into a FC port. Forcing the SFP+ module into a
port may damage the SFP+ module or the port.
• You must install the SFP+ module into a port before you connect the fiber-optic cable
• You must remove the fiber-optic cable from the SFP+ module before you remove the SFP+ module
from the port.
WARNING: When handling static-sensitive devices, take precautions to avoid damaging the
product from static electricity.

Removing SFP+ Modules

To remove SFP+ modules:
1. Remove the FC cable from the SFP+ module.

2. Unlock the SFP+ module latch. For SFP+ modules that contain wire tabs, unlock the SFP+ module
latch by pulling the wire latch outward 90°.
